Connect every pair of matching colored dots with a pipe — but the pipes can't cross, and you must fill every square on the grid. Six hand-made levels, from a gentle 5×5 up to a brain-bending 8×8. Plays entirely in your browser, nothing to install.
How to play: Press and drag from any colored dot to draw a pipe to its twin. Fill every square and connect every pair to win. Drag over an existing pipe to overwrite it. · Keyboard: ← ↑ → ↓ move · Enter/Space pick up or drop a pipe · Esc release.
